Answer 1

No basis for what you have heard. You can find differences between all sorts of groups (young & old; athletes & couch potatoes; white collar & blue collar; poor & wealthy; blacks & whites), but these are not genetic differences - the differences occur because of different diets, exercise, and access to medical care. The biggest genetic differences occur between males and females.
